What is plus?

+ Plus refers to a power product in 20%, 50%, 100% load, must reach more than 80% efficiency, with the full load when the power factor must be more than 0.9. Many people will be efficiency with the two values of PF mixed, for example, a mark 500W power supply, in 100W, 250W, 500W these three kinds of output, if the conversion efficiency of 80% calculation, requires AC input value of at least 125W, 312.5W, 625W. If the PF is 0.95, the input power is 131VA, 328VA, 658VA. In 500W view, with 80% efficiency of the power supply, alternating current input of 625W. Conversely, only 60% of the efficiency of the product, alternating current will need to input 500w/60%=833w. Therefore, the conversion efficiency of the high and low, directly become the most important power supply key.

The PLUS plan, launched by the U.S. Energy Agency, Ecos Consulting is responsible for a nationwide energy-saving cash incentive program. Initially, to reduce energy consumption, the system is encouraged to use a fully loaded, 50% load, 20% load efficiency of more than 80% and a power supply with a PF value greater than 0.9 under the rated load conditions when producing desktops or servers. From the U.S. government's own pocket, for the above requirements, desktop systems for each system Award 5 U.S. dollars, the server for each system is rewarded 10 dollars.

Now the world is advocating energy conservation and environmental protection, energy conservation and environmental protection are mostly carried out from two aspects: first, the search for new energy, the second is to improve the utilization of existing energy to reduce the current waste of resources and the impact on the environment. The United States Energy Program for the current low utilization of resources, the PC power to make a 80PLUS certification specification to improve the conversion efficiency of the power supply, to avoid unnecessary waste of resources.

Both desktop and server computers are required to convert AC AC power to DC DC through the power supply, which is used as a computer CPU, a hard disk, and a peripheral device. If the consumer uses the 30%~45% power supply, on the desktop computer, the date produces the electric power attrition, the year approximately will waste 125~150 kwh electricity; In terms of how the server is not shut down throughout the year, its annual waste of electricity will be more than 450-720 KWH (equivalent to a two-door refrigerator power consumption), so for a heavy use of computer enterprises or individuals, the full choice of the use of active power factor of efficient power supply, will help to save more energy and cost.

80PLUS is private investment, for the future environmental improvement, and energy saving and set up a strict standard, through the 80PLUS certified products, the factory will have a 80PLUS certification logo, and the factory can be rewarded from the civil organizations. Through 80PLUS products, energy saving, environmental protection, high efficiency, is the trend of electronic products drive.

Advantages

The programme was first implemented in 2003 and was formally incorporated into the Energy Star 4.0 standard in 2007. Up to today, 80PLUS has become recognized as one of the most stringent power-saving specifications. and ordinary consumers from the 80Plus certification can also obtain the following benefits:

1, reduce energy consumption, save electricity costs

2, reduce the calorific value of the computer, thereby reducing the thermal support

3, enhance the reliability of the computer, reduce the cost of computer repair and maintenance

Development and 80PLUS Certification

In fact, the implementation of the 80PLUS plan is divided into different stages, the so-called "roadmap", the ultimate goal is to ensure that all power supply conversion efficiency of more than 90%. But not once, but gradually increase the certification requirements.

Up to 2008, there are currently 5 stalls through the product, namely the plus White (Standard), bronze (bronze), silver (Silver), Gold (gold), white gold (Platinum) and Titanium Gold (titanium).

White Card Certification

July 2007 ~2008 Year June implemented. White brand certification as the original standard 80PLUS, it requires power supply in 20% light load, 50% typical load and full conversion efficiency of more than 80%.

Bronze Certification

July 2008 ~2009 Year June implemented. All approved power supplies must achieve the following indicators: 20% light load and full load conversion efficiency must reach more than 82%, 50% typical load conversion efficiency must reach 85%.

Silver Certification

July 2009 ~2010 Year June execution. On the basis of the bronze certification, the silver certification will be more stringent. It requires that the power supply in the case of 20% light load and full load, conversion efficiency must reach more than 85%, 50% typical load must reach 88%.

Gold Certification

July 2010 ~2011 Year June execution. It requires that the power supply in the case of 20% light load and full load, conversion efficiency must reach more than 87%, 50% typical load must reach 90%.

White Gold Certification

80PLUS white Gold certification in March 2011 quietly appeared, it is higher than the gold medal, the power supply in the case of 20% light load needs to reach more than 90%, 50% typical load must reach 92%, and full load of the case is 89%.

Titanium Gold Certification

The 80PLUS agency issued a new 80Plus standard in September 2011, the 80PLUS Titanium Gold medal. Even if the 80Plus agencies do not publish all this, we can guess a lot of things, such as 80PLUS Titanium Gold will be the first application in 230V room standards, 80PLUS Titanium Gold will have a higher conversion efficiency requirements, 80PLUS Titanium Gold medal efficiency must be the current power is difficult to reach the height.

Through the 80PLUS certification of power brands and models, 80PLUS official website provides inquiries services. Up to now a total of 1239 power supplies through the 80PLUS certification level. Among them, 830 power supply through the original 80PLUS certification, 318 power supply to achieve the 80PLUS bronze certification standards. Through the silver and Gold Certified power supply 69 and 22 respectively, less than 1/10 of the total. However, with the gradual implementation of 80PLUS certification, there will be more and more power to achieve this standard. In order to obtain the best power quality, but also for environmental protection to make contributions, we recommend that the vast number of readers in the purchase of power to choose as far as possible through the 80Plus certified power supply.
